I inherited a Mac FM database that they want converted to FM7 for windows.

The first 2 files I opened converted fine (dealers and customers). The invoice file is very large 47mb and the conversion starts, goes through multiple passes and ends with no errors. But is also does not create a converted file.

Thoughts?

What kind of errors does it give?

There should also be a conversion log text file that shows exactly where in the conversion process things go wrong. Based on that you can then clean up the original file and retry the conversion...

It does produce a log , although the format is kind of odd (includes lots of hex zeros).

At line 231 of the conversion log it says "unknown error". The actual conversion process justs ends with no error message on the screen.

What is the FM version of the original database? It's likely that there is some sort of latent corruption in the original file. You might want to recover the original file using the version of FM you are converting from (if you have it). The most conservative approach is recover the file, create a clone of the recovered file (an option under Save As...) and import the data from the recovered file.

Revisit the log, it's structured very logically. It goes through the same steps for every file so that with some careful examination you can find out where exactly the problem is: in the field defenitions, value lists, layouts, ...

The few times I've seen this was in very old files converted from FM2 through to 6 and each time the problem ended up being some corrupted objects on some layouts.
